实现效果:

　　

知识运用：

　　WindowsPrincipal类的IsInRole方法　　　　//确定当前主体是否属于制定的Windows用户组

　　public virtual bool IsInRole (WindowsBuiltInRole role)　　　　//属性为枚举值之一

　　

实现代码:

        private void button1_Click(object sender, EventArgs e)
        {
            AppDomain domain = System.Threading.Thread.GetDomain();     //获取当前域
            domain.SetPrincipalPolicy(System.Security.Principal.PrincipalPolicy.WindowsPrincipal);//将操作系统组映射到角色
            //获取当前系统组
            System.Security.Principal.WindowsPrincipal principal = (System.Security.Principal.WindowsPrincipal)System.Threading.Thread.CurrentPrincipal;
            if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.User))
                label1.Text += "当前用户为普通用户\n";
            if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.PowerUser))
                label1.Text += "当前用户为超级用户\n";
            if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.Administrator))
                label1.Text += "当前用户为系统管理员\n";
            if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.SystemOperator))
                label1.Text += "当前用户为系统操作员\n";
            if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.BackupOperator))
                label1.Text += "当前用户为备份操作员\n";
            if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.PrintOperator))
                label1.Text += "当前用户为打印操作员\n";
            if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.Replicator))
                label1.Text += "当前用户为复制操作员\n";
            if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.AccountOperator))
                label1.Text += "当前用户为账户操作员\n";
            if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.Guest))
                label1.Text += "当前用户为来宾用户\n";
        }
